[Q] Sim problems! - Desire Q&A, Help & Troubleshooting

I rooted my desire, and i am using Leedroid with launcher pro, and some apps and what have you, and although it seems to recognise my sim, and knows my phone number, it wont let me connect to my network (orange). any idea why? is it simply locked? or is it something less annoying?

come on people someone must have an answer, or atleast a hypothesis.
just to clear things up, i was given the phone, without a charger or anything, took the old sim out and tried it with mine, rooted it almost straight away, but i dont get signal at home anyway.

A friend of mine had the same problem. He went down to his service provider to get the sim card replaced and it worked. I also overheard while at htc's service center, the service staff giving the same advise to someone.

so i need a new sim card?

unlocked phone suddenly says 'invalid sim'

I broke and replaced the screen in my unlocked upgraded flashed-ROM wallaby and the unit now starts up and reports invalid SIM.
Is there any solution or should I re-flash the rom again and see if that works, hope for the best?
Try the SIM in a different (unlocked) phone, to make sure the SIM isn't fried. If the SIM is fried, you can get a new one from your provider. SIMs do get fried sometimes -- it happened to me a couple months back. Fortunately my provider (Cingular) has a shop just down the road from me, and they burned a new SIM in 5 minutes.
I apologise, I should have said
Sorry, I should have said, it does work in another machine and as I said, it did work immediately I used the xda flashing process to upgrade the ROM in this very unit before I dropped it.
Everything else in the new ROM seems to work which makes it infuriating that it wont recognise the SIM. I even tried calling T-Mobile and asking them if they could see the SIM on their network and they couldn't.
(I even have one of those SIM copying devices they send you free for some unknown reason when they want you to upgrade your service to some kind of higher level SIM card. I was wondering if I should try to use it again but as mine does work, this, like the whole copying device, seemed a bit academic)

No Sw. Dead radio - any way to diagnose?

My 2 month old One X seems to have developed a problem today, with it's GSM/UMTS radio. Was working fine this morning in Dublin. Caught a ferr y back to the UK and it was still fine but by the time I got to my office in Chester, it was showing no service. I just put it down to a local issue with the Vodafone network. But, on the 200 hundred mile drive back to London, despite rebooting and trying to force it to re-register as GSM, WCDMA in GSM/WCDMA modes, I've still not managed to get anything other than No Signal. Clearly not a general Vodafone network problem as the UK news and internet sites would be all over it.
I got back home and tried the other Vodafone SIM that I use in my Galaxy Tab (screwing up the SIM slot in the Tab, in the process) but exactly the same problem. I've spoken to Vodafone and despite me trying the other SIM, they've just said it looks like your SIM isn't registering with the network, so we'll send another out. All good except I'm off on holiday tomorrow.
I'm wondering if the radio "chip" itself has gone AWOL and wondered if there is any way to diagnose that on the handset itself? Any ideas if that's possible or anything else I can try to diagnose the issue?
Failing that, I guess it needs to go back to HTC for repair/replacement. Anybody know how warranty repairs work and how long it's likely to take to resolve and anything I should do with the phone beforehand?
You need to try your sim in another phone to eliminate the sim card
If its the same in another phone its the sim if it works fine its the phone

[Q] no cell service with activated SIM card

Alright, here's my issue. I got the phone unlocked about three months ago, worked perfectly. I get great signal with AT&T, always have. I don't have a data plan or anything, phone gets wifi fine.
One day I stopped getting cell service. It appeared on the phone as the circle with the line through it. I thought it was odd since I always get good signal. Still got wifi fine. Took the SIM out and put it in my nokia, full bars. Tried playing around with the APN settings, nothing. Reformatted the phone, nothing.
Went and talked with an AT&T guy and he gave me a new SIM card. He put it in my phone, unactivated, and it worked great, showed up with full service. Once he activated the SIM, it went back to saying no service. It doesn't say no SIM, just that I don't have any signal at all.
When I take the SIM out and power on the phone, I get the no SIM error and it shows that I have full signal. Once I put it in, nothing.
Right now I am just using it as a wifi device. I am not really sure what I should do, and I can't return the phone.
Any help would be greatly appreciated.
my wife's Glide is getting the same problem behavior as outlined in this thread. With a new phone, new SIM and new battery we see the no network icon and Service State=unknown in phone status. No sim card error anymore, just no network. I'm going to take the phone in to the warranty center for another new battery and SIM card. I'm not optimistic. Add to that ever since we got the Glide, the phone would not ring or show missed calls sometimes when people really did call.
The AT&T warranty center offered my wife a different phone (new) as a replacement, but the Glide is the only decent Android phone with a keyboard and she has to have a keyboard.

[Q] No SIM error on stock with root

I have root, thats it, i get NO SIM in the notifications and have no data. Every now and then I would be able to restart to fix it,but now it seems its working either. ICCID is unknown in About phone. Everything else seems alright.
This is almost a brand new phone, only rooted. Had no new ROM installed on it. I restored it to the very first backup i made after rooting, same issue. I have a pending 4.3 update,which I have not updated yet.
Any idea what's going on ?
No one?

My son was having issues with his HTC One's SIM card. Data was sporadic, no LTE, and he would get no SIM card errors. We took it in to the Sprint repair center in the area and they first tried blowing out the SIM card slot but ended up putting in a new SIM card which fixed the problem.
Hopefully the person who looks at your phone is competent as we had to make a few trips as we were told at one point that we didn't even need a SIM card since we were not going Global - this older guy was wrong. We ended up having this young woman take a look at it and she swapped it out ASAP and we were good. I'm going on a bit but I was somewhat floored that their repair tech gave info that was just wrong. I've had to go back a few other times (for other reasons) and I avoid that dude at all costs (straight to the young woman).
Unfortuantely, on note 2 the sim card is not even accesible. Its buried/sealed inside, unless sprint techs have a way to access it.I am surprised this is such a low occuring issue, that no one in this forum has this.
Same thing
Same thing happened to me 2 weeks ago, i had to order a new card

The "techs" there are a joke. The only people who can REALLY help are devs who they probably keep locked away in a safe house abroad. There hasn't been a single time when a phone carrier tech was remotely helpful for me.
And the SIM is on the same module as the SD card. IIRC they can swap out this entire module. How will they replicate the same iccid onto the new one? No clue. If they replaced it and your issue was fixed though they did it somehow. Or else your authentications would be all messed up (meid> mdn>min>HDR AN>profile 0 and 1>iccid...probably more I'm forgetting)

Unlocking help

I have an S2 i9100p which was originally locked to orange under contract, before the contract in late 2013 expired I had it unlocked and everything worked fine until one day it stopped, completely blank, not even switching on... I sent it back to a registered Samsung Repairer and when i got it back everything was different due to the repairs they made, the android version was different to the version i had originally and the phone was no longer unlocked... I have since tied many methods, bought a code online, still locked... on 3 seperate occasions i took it to a local unlocking shop and each time they couldnt do it and couldnt explain why... I have also rooted it with frama root as its the only rooting software that has seemed to work since the repair and then tried the samsung unlock app from this site in the playstore, some apps dont even recognise the phone as a samsung settings for about device > status under phone number say its unknown but recognises the device name and model, imei, etc.. but still no avail to unlocking.... can anyone shed any alternate solutions on how i can unlock this? I dont wanna take it back to the samsung place cos they are so far away and want to charge £50 to try, not to unlock it, to try.... please someone gimme a solution as orange dont provide a good enough service for the area i live and my general usage needs require more than they offer on a payg orange sim (the only sims that work)... ive periodically tried different cards in the hope that it unlocked magically but always get the same screen sim network unlock pin which i dont have , help before my phone becomes a high speed projectile
